From 1af1e8a39dc0fab5e50f10462c636da8c1e0cfbb Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Sun, 3 Dec 2017 19:09:41 -0800 Subject: xtensa: move fixmap and kmap just above the KSEG The virtual address space between the page table and the VMALLOC region is big enough to host KASAN shadow map and there's enough space between the VMALLOC area and KSEG for the fixmap and kmap. Move fixmap and kmap to the gap between VMALLOC area and KSEG, just above the KSEG. Reorder entries in the kernel memory layout printing code. Drop duplicate PGTABLE_START definition, use XCHAL_PAGE_TABLE_VADDR instead.
